Indonesian seas - List of fishes

At night, the yellowbanded sweetlips hunt benthic invertebrates in sandbanks and seagrass beds. During the day, they rest in the crevices and recesses of the reefs. This tropical species, which can grow over 70 cm, is targeted by fishermen in many Pacific Ocean islands.

The Emperor Angelfish is found from the Red Sea to the Great Barrier Reef. Juveniles hide under reef overhangs or in holes in outer lagoons, while adults prefer caves in coral-rich areas. These fish feed on sponges and form pairs for reproduction.

The blue shark, also known as the "blue skin shark," is a pelagic predator found in temperate and tropical marine waters, with occasional sightings near the coast. Its wide distribution, however, is threatened by overfishing. Recognizable by its blue back and white belly, this sleek-bodied shark mainly feeds on small fish, mollusks, cephalopods, and sometimes birds.

The peach fairy basslet is found from the Red Sea to the Great Barrier Reef. Juveniles hide under reef overhangs or in holes in outer lagoons, while adults prefer caves in coral-rich areas. These fish feed on sponges and form pairs for reproduction.

Pseudobalistes flavimarginatus, better known as the "yellowmargin triggerfish" due to the coloration of its body, is a fish belonging to the balistidae family. It is found in tropical waters of the Indo-Pacific. It can be encountered on reefs and estuaries, but can also be observed on slopes and in lagoons.

This fish lives near diadem-urchins. At the slightest danger, it takes refuge between the long spines of sea urchins. The male guards the eggs in the mouth until they hatch. It is threatened in the wild because of fishing for the aquarium trade. This species breeds in captivity.

This dartfish is easily recognizable by its two-tone blue and black body. Like its counterparts, adults live in pairs in burrows they dig in the substrate.
